Abstract:
-The possibility of using 5-(4-hydroxy-3,5-dimethylbenzylidene) thiazolidine-2,4-dione (HDBT) for photometric 
determination of cobalt(II) has been studied. The cobalt(II) complex is extracted into chloroform in the pH range 8.0-9.3. The maximum 
analytical signal for the comp-lexation of cobalt with HDBT is observed at 532 nm. The molar absorption coefficient is 2.35 × 104. 
The ratio of components in the complex is Co:HDBT = 1:2. The extract of the cobalt comp-lex obeys the basic law of light absorption 
at a concentration of 0.5-10 μg/ml. Based on the results of spectrophotometric studies of cobalt(II) with HDBT, methods for 
determining cobalt in different objects have been developed.
